Figure 2.

Four representative OBP gene clusters present in silkworm. Four gene clusters are located on scaffold2529, scaffold2902, scaffold2943 and scaffold3052, respectively. Each gene is depicted by arrowheads presenting the orientation of transcription in the scaffold. Three non-olfactory genes between Obp1 and Obp2 in scaffold3052 have been omitted for clarity.
